Don't use dvd player!

The firmware in some DVD drives used by Apple keeps VLC from bypassing the region code. So it will depend on which drive is installed in your Mac Pro. It is not Apple specific, drives from these suppliers keep VLC from bypassing the region code in systems running Windows or Linux. But the region coding can be bypassed on many/most drives using VLC.
